Fish Oil Supplementation as an Omega-3 Fatty Acid Source during Gestation: Effects on the Performance of Awassi Ewes and Their Offspring.

The primary aim of this research was to assess the impact of supplementing fish oil into the diet of pregnant Awassi ewes on various aspects of the dam's productive performance, offspring birth weight, colostrum yield and quality, milk production and composition, postpartum offspring performance, and the composition of fatty acids in milk. In this study, two different fat sources, namely palm oil (PO) and fish oil (FO), were utilized, with both being included at a rate of 2.4% of dietary dry matter (DM) during the initial 65 days of gestation (early gestation stage), and then at 2.

Fish oil supplementation as an omega-3 fatty acid source during gestation: effects on the performance of weaned male goat kids.

The aim of this study was to evaluate the effects of fish oil supplementation, as an omega-3 fatty acids source, to ration of does in the different periods of pregnancy on the fattening performance of kids after weaning. Eighty German Fawn × Hair crossbred does were randomly divided into two groups; half were given fish oil in the first half of pregnancy (FO group), while the other half were given saturated fat (PF (control) group). Then, the goats in the FO and PF groups were randomly divided into two subgroups, and half of the goats were fed fish oil during the second half of pregnancy (FO-FO and FO-PF groups), while the other half was fed saturated fat (PF-FO and PF-PF groups).

Post-mating diclofenac vs. carprofen treatment on serum progesterone levels and reproductive outcomes in Hungarian-Merino ewes during the non-breeding season.

The maternal recognition process is crucial for the establishment of healthy pregnancy. In this process, anti-luteolytic applications are one of the main reproductive strategies to manage the embryonic losses and maximize reproductive profitability in farm animals. The aim of this study was to investigate the efficacy of post-mating NSAID treatments on reproductive parameters (pregnancy rate, lambing rate, multiple birth rate, litter size) and serum progesterone levels in ewes stimulated with progesterone non-breeding season.

Effects of different degrees of deacetylation and levels of chitosan on performance, egg traits and serum biochemistry of laying hens.

The present study was conducted to evaluate whether the deacetylation degree of chitosan (low: 70% vs. high: 90%) and its dietary level (0, 200, 400, 800, 1600 mg/kg diet) would affect laying performance, faeces viscosity, egg quality, egg and serum biochemistry of layers. For the experimental feeding period of 8 weeks, 140 four weeks old Hisex Brown layers were divided into 10 treatment groups, comprising 14 birds each.
